Title: Machine for Coating Interior of Containers
IPC: B05B13/06
Filed: 1966-12-29
Abstract: 1,156,530. Coating apparatus. COORS PORCELAIN CO. 29 Dec., 1966 [10 Jan.. 1966], No. 58208/66. Heading B2L. In a machine for coating a cylindrical container, mechanism for rotating the container while in coating position, comprises a wheel 15 rotated in one direction and, having a peripheral surface in rotation producing contact with a side surface of the container 27<SP>1</SP> and a flexible belt 35 driven in the direction opposite the direction of rotation of the wheel 15 and located to have rotation-producing contact with the opposite side of the container. Containers 27 are fed down a chute 29 into pockets 28 of a star wheel 16 driven intermittently. In such pocket 28 the container rests in contact with a guide roller 23 and a pair of guide rollers 24 arranged on adjacent arms 22 so that they bear on the container in an axially spaced apart manner. Rotation of star-wheel 16 brings each container in turn to the position 27<SP>1</SP> where it is brought into contact with the wheel 15 on one side and a pair of axially spaced apart belts 35 on the other side so as to rotate the container without deforming pressures acting thereon. The belts 35 run in parallel directions but at a slight angle to a direction perpendicular to the axis of the containers to maintain the containers in contact with a spinner base to prevent any tendency to move in an axial direction. In the position 27<SP>1</SP> and whilst the container there is being rotated coating medium is sprayed into the container by suitable nozzle means. The belt assembly is mounted on a bracket 45 with adjusting means 46, 47 to allow adjustment of the positions of the belts relative to the containers and means are provided for rendering the spray nozzle inoperative in the event of no container being moved to the position 27<SP>1</SP>.

Title: A method and a device for carrying out a metallurgical process
IPC: F27D27/00
Filed: 1967-12-22
Abstract: 1,216,489. Agitating metal melts. INVA A.B. 22 Dec., 1967 [22 Dec., 1966], No. 58410/ 67. Heading B1C. [Also in Divisions C7 and F4] In a metallurgical process molten material is treated (e.g. degassed) in a container which is given 'an oscillatory motion such that the material is projected so that it is broken up into particles while being treated. As shown in Fig. 1 the container 1 forms the bob of an inverted rigid pendulum and is rocked about a fulcrum 10 by a crank 11, Fig. 3. Inlet and outlet channels 2, 3 have openings below the level of the melt in tundish 4 and ladle 5 at positions on the axis of fulcrum 10. Material lies along the side of the container as at 7 and is then projected as at 8. Vacuum connections for degassing may be made at V, Vh; there may be an apertured dividing wall 13 between zones of different reduced pressure. If degassing is being carried out, the melt in tundish 4 will be lighter than that in ladle 5 and the difference in densities will cause passage of the melt through the apparatus. This may be assisted by injection of gas into the duct 2 as indicated by the bubbles shown. In an embodiment as an iron refining furnace (see Figs. 7 to 9, not shown), the container is charged with liquid pig iron, air or oxygen, are concentrates and lime where indicated, waste gases are withdrawn at both ends, and refined steel I and slag S are withdrawn over a sill (72) to a tundish (75). In a modification of this embodiment (see Figs. 10 and 11, not not shown) the furnace is provided at each end with a detachable regenerator for preheating the air supply. The regenerators have their own bearing fulcrums (106) coaxial with those (76) of the furnace and are filled with regenerative material to the level of the bearings so that its surface is not thrown about. Air is supplied and waste gas removed alternatively through pipes (105). Instead of being oscillated about a fulcrum the container may be vertically reciprocated by supporting hydraulic or pneumatic cylinders (62) assisted by a buffer and recuperator (41, 42, see Figs. 4 to 6, not shown).

Abstract: 1370906 Drawing composite glass filaments OWENS-CORNING FIBERGLAS CORP 17 Dec 1971 [28 Dec 1970] 58697/71 Heading C1M In the formation of light-conducting glass filaments having a higher refractive index glass core and a lower refractive index glass sheath, heat-softened glass for the core is supplied to a first orifice and heat-softened glass for the sheath to a second orifice which is larger than and surrounds the first orifice to produce a combined stream of core-sheath glass which is cooled by a cooled surface located adjacent the combined stream which is then attenuated to a light-conducting glass filament. Raw materials for the two glasses are supplied from separate hoppers (10) (12) to melting receptacles 14, 16 which feed the molten glass through passages 94, 96, to compartments 18, 20, the compartment 18 being surrounded by the compartment 20. Rows of nozzles 24 project from the bottom 23 of compartment 20, each nozzle 24 comprising an outer tube 68 and an inner tube 62 which extends upwardly at 63 through compartment 20 to compartment 18 to form an inner passageway 56 for the core glass and the annular passageway 58 between tubes 62, 68 has holes 70 through to compartment 20 for the sheath glass. The streams 67, 72 of the core and sheath glass form a combined stream 26 in a core shape which is drawn to a filament 32. Preferably the inner tube 62 extends slightly below the outer tube 68. Between the rows of nozzles 24, metal fins 74 extend substantially at right angles to the bottom, wall 23 for a depth "d" which is equal to or greater than the depth of the core of stream 26. The fins 74 extract heat from the stream 26, the fins 74 being supported from a water-cooled member 76. The fins 74 are preferably at a distance "h" below the wall 23, which is level with the end of tube 62, so as not to chill the streams 72 before merging of the streams which would cause the stream 72 to form an oval shape. However if this is desired, the fins 74 may be positioned higher. The melting receptacles 14, 16 have platinum walls 82, 84 and current conducting elements 86, 88 with perforations 90, 92 and the compartments 18, 20 are also of platinum. Current is supplied to elements 86, 88 by bus bars 120 and 122 and to compartments 18, 20 through terminals 114. A circuit for control of temperatures is disclosed. The core glass is preferably in the following ranges in percentages by weight: SiO2 30-32; Al2O3 7-8; B2O3 2-7; K2O 5-10; BaO 46-49; Sb2O3 0À01-0À05. The sheath glass is preferably in percentages by weight, SiO2 63-65; Al2O3 5-6; CaO 2-3; MgO 0À5-1; B2O3 12-14; Na2O 6-8; Li2O 3-5; F2 1-2.

The nozzle 18 of the amplifier last stage has disposed directly opposite thereto a collector nozzle 19, the latter nozzle being connected to a transducer 29. Taking P 24  to represent the pressure at power nozzle 14 as supplied by source 24, then it is preferred that the power nozzles are connected to sources of pressure which satisfy the relationship: In operation, if the control pressure within nozzle 13 is greater than the same within nozzle 12, power jet 34 issuing from nozzle 14 is deflected accordingly and so acts to deflect power jet 35. Subsequently jet 35 deflects jet 36 which in turn deflects jet 37. The last mentioned jet deflects power jet 38 and so alters the proportion of liquid fluid collected in nozzle 19. The entire amplifier is contained within a closed box-like chamber 11 to eliminate extraneous disturbances. Fig.3, (not shown), depicts a modified amplifier wherein the various power nozzles are arranged symmetrically about the last stage power nozzle, the latter being acted upon by two power nozzles of the preceding stage and being directed towards a pair of collector nozzles.

An inert gas line 6 from a pressure gas cylinder screws into a threaded plug 3 fitted in the gas inlet, thereby opening the valve 5, and includes valves 7, 8 and a branch pipe 11 provided with a valve 12 and a hydrostatic excess pressure valve 13. In operation, the valves 7, 8,12 are opened to allow the inert gas to flush the pipe system which is then coupled to the plug 3. When a closure 4 is removed from the outlet, gas passes through the vessel until the guide sleeve 16 is screwed into the outlet and the discharge pipe 17 is inserted. The valve is then closed and the valve 7 is opened further so that the flow of gas forces the material through the discharge pipe 17. A delivery pipe 18 connected to the pipe 17 is made of transparent plastics material and is provided with an earthing cable for use in conveying inflammable material.
